OF NEW YORK, N. Y.

PLASTIC PILE.

To all whom it may concern:

Be it known that I, Josnrn LINDEMAN, a citizen of the United States, residigg at New York city, in the county of New ork, State of New York, have invented certain new and useful Improvements in Plastic Piles; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in concrete piles, and has for its object to provide a device of this character which can be driven into the river bed without the danger of cracking the cement body when being driven.

A further object of the invention is to provide a concrete pile having reinforcmg elements of novel form embedded therein so as to strengthen the same.

A still further object of the invention is to provide a pile of this character so constructed that the same can be conveniently molded into the form, and further to provide novel means for arranging the reinforcing elements previous to the application of the cement body thereto.

With these and other objects in View, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which 1 Figure l is a side elevation of the com plete pile.

Fig. 2 is a longitudinal sectional view through the mold.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Fig. 4 is a sectional view on line 4-4 of Fi 2.

Fig. 5 is a side view of the preferred form of mold.

Referring to the drawing 1 indicates the dolly of the pile, said dolly being formed from wood and has its lower end provided with an extension 2, whereby the annular shoulder 3 is provided, said dolly being further provided with an annular shoulder i the purpose of which will appear later.

A ring 5 is employed and receives the extension 2, said ring having its under surface provided with a circular series of eyes Specification of Letters Patent.

Application filed April 30, 1917. serial No. 165,451.

' 6. A metallic band 7 is engaged around the ring 5 and adjacent part of the dolly l and has its upper edge engaged with the shoulder 4, said ring serving to prevent the band and dolly from splitting when subjected to blows during the driving of the pile.

The tapered point 8 is provided, and is preferably formed from metal, but if desired it can be formed from wood as are the dolly and ring 5. The point has a circular series of eyes 9.

Between the ends of the pile are several rings 11, each having eyes 12 as best seen in Fig. 3. The end elements are connected by a metal reinforce 10, preferably a single length of wire rove through their various eyes so as to form two sets of strandsone an outer shell or cage wherein all strands are longitudinal and substantially parallel, and the other an inner core where in all strands converge to the axis of the structure near its midlength and there cross each other. The strands in the outer set preferably pass through the eyes of the rings. If a single wire is used as suggested, it can be attached to one end eye as 6, led straight down through several ring-eyes 12 to the corresponding end eye 9, then led up and diagonally across to an upper eye 6 about opposite the first eye, then again straight down, and s0 0n-thus making the successive stretches of the wire alternately constitute strands in the two sets. However, this can well be left to the user, as he may prefer to employ separate lengths for the two sets or reinforcing elements.

After the reinforce has been properly arranged the dolly 1 is removed so that the cement in liquid form can be poured through the opening of the ring 5, after which it hardens'and firmly embeds therein the reinforcing element. The strands are held against distortion when the cement is poured in the mold by the rings, 11, which are provided with eyes 12 for engaging the strands. It will be of course understood that after the strands have been properly connected with the dolly and point that this skeleton formation is placed in a suitable mold so that the strands and rings will be embedded in the cement and out of sight the mold being removed before the pile is driven.

From the foregoing description it will be seen that a pile has been provided which is particularly adapted for use in connection with docks, Wharfs or the like, or in any place Where it is desired to use which Will last indefinitely.

The preferable form ofmold 13 is shown 7 in Fig. 5, and consists of hingedly connected sectlons 14, said sectlons having their free edges provided \Vlth longitudinal flanges 15, one of which has pivotally connected'thereto a latch 16 Which is operable to hold the flanges in clamped engagement and the sections in confronting relation. The sections of the mold are so shaped as to produce a tapered pile, and are provided with Wooden linings 17 so the cement will dry more quickly,

e What is claimed is V A pile including spaced end elements, circular series of eyes on the inner faces there- 7 of, a pluralityof rings arranged in spaced a pile relation to each other between the end elements, each ring being formed With eyes arranged in a series therearound, and a reinforcing strand rovethrough the eyes on the-end elements and rings to provide a shell of longitudinal stretches, and led from each end eye across to an eye substantially opposite at the other end to form diagonal stretches so disposed as to cross each other substantially at the midlength of the pile; and a plastic.fillinginclosing all stretches and rings.

In testimonyiwhereof, I ath x my signa time, in the presence oftwo witnesses.
